Hi Clemens I can't find any other sequencers with sync implemented properly... Rosegarden doesn't accept any MIDI sync in on my system, and does not seem to set a correct out as the external sequencer shows it's play light go on but does not catch up sync until stop is pressed. MusE has rock solid sync out and I am only seeing the problems on sync in. I do not know of another software I can use to compare to try and identify if it is the driver or the software. Let me know if you know of one. Takashi, once sent me a cli based program to test this, but I know longer have it. (It was on a 2.2 kernel so probably wouldn't work anyway) cheers Allan On Thu, 2006-12-07 at 19:40 +1100, Allan Klinbail wrote: > Hi Clemens, > > I haven't tried the other 2 yet (will do today or tomorrow), however I > have done some more extensive testing today.
